文件上传 乱码
所有字符集都设置的是utf8，但上传文件后在文件目录下发现中文文件名乱码，然后就在上传前把文件名转为了GB2312码，这时候文件名可以显示中文了，但是数据库存放路径的时候不能插入了，我就把那张表改成了GB2312的字符集，按理说这样就可以了吧，还是插入不了？怎么办回复讨论(解决方案)
这里涉及两个概念，系统的编码和字符的编码
不知道你上传前是什么系统，如果是windows（98以后），选了"gb2312"编码实际上是cp936（相当于GBK）编码
而数据库的字符编码gb2312和gbk并不相同，汉字少很多，应该选gbk编码
还不行的话就要考虑其他因素了，如果服务器是windows，那是个麻烦事，因为php目前还不能有效处理windows下unicode路径??假设你的全路径有任意一个字符超出了字符集，windows是采用混合编码记录路径的；而*nix则是统一以utf-8编码记录路径，所以问题不大
csdn的开发人员又做多余的事了，帖子的分段又没了，唉……
说一个解决思路楼主试一试
还是全用UTF-8,上传后在PHP文件内再强制转换一次 上传后检测文件名是UTF-8还是GBK还是GB2312 然后统一转换为UTF-8
参考 http://www.cnblogs.com/rosenia/archive/2013/05/20/3088146.html 数组多加一个GB2312
然后再存

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
